3 Claims. 1

This invention relates to incinerators, and

more particularly to the combination of a trash burner and incineratorfor garbage disposal.

The principal objects of the invention are to providea'trash burnerhaving a garbage disposal compartment whereby the burning of the trashwill dehydrate or dry out the garbage so that suchgarbage may be burnedin the trash burner;

to provide a mounting forthe garbage container whereby the container maybe rotated to dump the garbage after it has been dehydrated into theburner compartment; to provide means for applying additional heat abovethe garbage container in the fire box; to provide a fire chamber spacedfrom the housing of the burner to provide insulationfor the housing; toprovide a mounting for the grate in the trash burner which may berotatedto cause the ashes to filtrate therethrough; to provide draft tothe fire box of the burner; and to provide a device of this charactersimple, economical to manufacture and efficient in operation. v

In accomplishing these and other objects of the present invention, Ihave provided improved de- .tures-oflmyinvention comprising a housinghaving-a rear wall 2,.front 3, sides'd and:5,'and top .6.The-top-ttisprovidedwith a forwardlyslopingrportion 1 provided witha'door 8 hingedto ithe-stop-firasindicated at fl. The housing ispreferably madeof sheet-metal and fastened at the corners by providingflange portionsby suitable .means, such as welding, bolting orthe like.The .top-is fianged tofit over the outside edges of the housing and thefrontiportionofthe flange sloped to accommodate the hinges 9 (Fig. 1)

(30., Kansas City, Mo.,

from the side walls 4 and 5 to form an insulation space around the firechamber. The top of the rear wall H is provided with an outwardly turnedfiange 14 for attaching to the wall 2, and the sides l2 and I3 of thefire chamber are fastened at their bottom edges to the front wall of thehousing by lateral flanges l5 .as best illustrated in Fig. 2. It will benoted that the fire chamber is thus spaced from the rear and side wallsof the housing so as to eliminate excessive heat through the outer wallof the housing. A wall it is attached to the top 5 of the housing bywelding or other suitable means as indicated at I1 (Fig. 2) and spacedfrom the top to form an insulation space to prevent excessive heat fromreaching the top '6. A smokestack i8 is provided which extendsthrough'the top 5 and intermediate wall F6 to the fire box It) for theelimination of smoke and fumes therethrough. Located within the housingand forming a bottom for the fire chamber i0 are grates i3, 29 and 2|.The grates l9 and 2| have their rear ends extending through the wall .Hof the rear of the fire box andare attached to the rear wall 2 of .thehousing by brackets 22 and 23. The brackets maybe secured to the rearwall 2 in any. suitable manner, such as by welding or bolting. The frontends of the brackets are attached directly to the front 3 by brackets.24 and 25, the front and rear brackets forming a suspension for thefire chamber in the housing. The grate 20 is provided with a central rod25 rigidly secured to a frame 21 which comprises slide rods 28 and 29and-end portions 3i} and Si. The rod 26 extends through the rear wall llof the fire chamber and through the front wall 3 of the housing. Therear endoftherod is loosely mounted in a bracket 32 secured to the rearWall 2 of the housing and the forward end of the rod 25 extends throughthe wall 30f the housing and is provided with a .handle '33 rigidlysecured to the rod in any suitable manner for rotation of the grate 20to cause sifting of the ashes therethrough. While the grates are formedso that ordinarily the ashes will sift therethrough without assistance,in burn- ,ingof magazines or like articles it may be necessary to stirup the trash by shifting of the grate.

While I have shown only the central grate as rotatable, it will beobvious that all of the grates could be rotated if desired withoutdeparting from the spirit of my invention.

Located within the fire chamber preferably substantially to the rearthereof and above the hire grate, is a garbage receptacle 34 mounted on3 the sides I2 and I3 of the fire chamber by brackets 35. The bracketsare flanged as indicated at 36 and shaped to form a V-shaped bearing 31for the garbage receptacle.

The garbage receptacle 34 is cylindrical in form and preferably has ends38 secured to a shaft 39 which extends through the ends 38 atsubstantially the centers thereof. The receptacle is provided withlongitudinal partitions 40 dividing the receptacle into compartments 4|,42, 43 and 44. The outer edges of the partitions 40 are turned laterallyto form flanges 45 so that they will fit in the ends 38 of thereceptacle which are also flanged as indicated at 46 (Fig. 1). Theflange 45 will also aid in retaining the garbage in the compartments.The shaft 39 is preferably substantially square as best illustrated at41 (Fig. 2) and the ends extending through the cylindrical ends 38 ofthe receptacle are adapted to engage in the V-shaped bearing 3'! of thebrackets 35 so that the edges of the shaft fitting in the V-shapedgroove will prevent the receptacle from rotating until moved by theoperator as later described.

A bottom 48 is provided for the ash box 49 having a door 50 hingedlyconnected to the front wall 3 by hinges 5| and having a handle 52.Formed integrally with the bottom 48 and extending downwardly therefromare legs 53 and 54. While I have here shown the legs as solid andextending across the front and rear of the housing, any suitable legsmay be provided. Brace bars 55 are provided at each corner of the bottomof the housing to lend rigidity to the device.

Perforations 56 are provided in the sides 4 and 5 of the housing toallow air to enter the ashpit to provide a draft while burning the trashon the grates. If desired, the door 50 may be opened to add additionaldraft to the fire chamber. A lug 51 is provided in the lower corner ofthe door 50 to extend slightly beyond the side 4 of the housing. A latch58 is pivotally mounted on the side for the housing as indicated at 59and having a slot 60 in the outer end thereof adapted to enash pit israised for cleaning out the ashes, the locking member 6| may engage inthe notch 62 of the lower edge of the door as best illustrated in Fig.1.

Extending through the side 5 of the housing and the side ['2 of the firechamber is an elongated burner 63 preferably adapted for the burning ofgas as fuel to dehydrate the garbage in the Trash, such as paper orother dry material, may placed on the grate in the fire chamber throughbage for drying, said rack chamber has dehydrated or dried the garbagesufiiciently to allow burning thereof, the receptacle may be rotated bythe hand of the operator to dump the dehydrated garbage onto the gratein the fire chamber for burning. The next compartment of the receptaclemay then be available for further storage of garbage for dehydrating.

To facilitate burning of the trash in the fire chamber the center grate25 may be rotated by the handle 33 and also to sift the ashes to the ashchamber. The ashes may be removed from the ash chamber through theopening 6! in the front of the housing by raising of the door 50.

While I preferably form my device from sheet metal or the like, it willbe obvious that any suitable material may be used and the various partsflanged and secured together in any suitable manner.

My device may be adapted for either inside or outside burning of trashand wet material. When it is desired for operation in an enclosed space,the smokestack is available for disposing of fumes or smoke.

It will be obvious from the foregoing that I have provided an improvedincinerator in which dry material as well as wet material may bedisposed of by one operation.
